1 Introduction The cost of a standard subway ride is $2.75. You can purchase individual rides by adding money to your MetroCard or you can purchase an unlimited number of rides for a 7-day period for $33 (or a 30-day period for $127, but we will ignore this for now in order to simplify the problem). What is the lowest price you can pay to purchase the number of subway rides you need for the week? 2 Objective The goal of this activity is to develop a function, named min_sub_cost, that determines the lowest cost to buy n subway rides to be taken in a 7-day period. This function will then be implemented in Python. Assume that your Python function will accept as an input a positive integer n that represents the number of subway rides you plan to take in a 7-day period. It is guaranteed that I n
